Expand 8(5-r)/5=-2r as indicated: 40 - 8r
----------- = - 2r
5
Multiply both sides by 5, obtaining 40 - 8r = - 10r
Combine like terms: 40 = - 2r
Divide both sides by -2: -20 = r
The solution to 8(5-r)/5=-2r is -20. Verify this by subbing -20 for r in the given equation.

Answer:x=61
Step-by-step explanation
856−5x3{131}=2
8(x−9)+5(5−18)+1(15−6x)=2
8x−72−65+15−6x=2
2x=122
x=61

Answer with Step-by-step explanation:
The given figure is a cuboid.
We know that surface area(S) of cuboid is given by:
S=2(lb+bh+hl)
Where l is the length, b is the breath and h is the height
Here, l=12 mm
b=6 mm
and h=(7+2) mm=9 mm
Surface Area= 2(12×6+6×9+9×12)
=2(72+54+108)
= 2×234
= 468 mm²
Hence, Correct option is:
C. 468 mm squared
